Future computing in particle physics

Jun 15, 2011, 2:00 PM → Jun 17, 2011, 7:00 PM GB

Cramond Room (e-Science Institute, Edinburgh)

Recent developments in computing and software architectures have resulted in huge potential for accelerating applications used in experimental particle physics. This is an ideal time to investigate how a significant performance boost can be achieved by the effective use of many-core and GPU architectures in a distributed computing environment, as well as utilising emerging I/O and storage technologies. This workshop aims to discuss what has been done so far in the field and what potential future development areas are feasible.
